REFRIGERATOR-DOOR CONSTRUCTION.

Application filed June 25, 1923. Serial No. 647,598.

To all whom it may concern.'

Be it known that I, LLOYD G. COPEMAN, a

citizen of the United States, residing at doors and has for its object a refrigerator lining construction of cast tile and provided with means for preventing the moisture condensed on the door from draining out the side of the refrigerator so as to get into the joints of the door frame or leave a wet spot on the floor outside the door.

In the drawings:

Fig. l is a fragmentary inside elevation of the tile.

Fig. 2 is a vertical section on the line 2 2 of F ig. l.

Refrigerator doors are ordinarily built up of a wooden block construction forming a thick stepped door which is ordinarily lined with zinc, galvanized iron. or some form of enamelled metal. It is the object of the present invention to completely do away with this built up construction which is open to difficulty if moisture gets into the joints that swell with the moisture and shrink when they become dry, finally pulling to pieces and also making an unsightly and unsanitary perishable structure.

In place of this construction I cast a hollow tile structure which is formed of a concrete,

porcelain, or stone material which is originally semi-fluid but which after the casting operation becomes a solid stone. This construction may be made of various concrete composition materials; I prefer to use an cuide-chloride cement composition. This is preferably composed of magnesium oxide,

sand (crystal flake) soft silex (ground flint),

ground asbestos,

chloride, 30 Baume.

hard stone when lithopone and magnesium This makes a strong it sets. This I preferably cover on the inside with some suitable filler material which will lill up any pores or depressions and then coat the same with enamel, preferab ly air drying enamel of the pyroxylin group, such as the well known Pyrolin put out by the E. I. Dupont de Nemours Co. of Wilmington, Delaware.

One of the special-features of this tile is that there is cast integral therewith, a drip flange a which protrudes down below the bottom of the pyramidal inside portion of the tile. any suitable die What I claim In order to accomplish this I use or mold.

l. In a refrigerator construction, a door lining in the form of a hollow tile block provided with a drip flange.

2. In a refrigerator construction, a door lining in the form of a hollow tile open on one side and having on the inside face an integral extension forming a drip flange.

8. In a refrigerator construction, a door lining in the form of a molded hollow tile having one side open and the other side pyramid al with the inside facing of such tile in the form of a hollow stepped block provided on its inside face with an 'integral depending drip flange.

In testimony w hereof,I affix my signature. LLOYD G. COPEMAN.
